Directions: Place eight long-stemmed wine glasses on the counter. In a stand-up mixer, using the whisk attachment, whip softened cheese and yogurt on high until smooth, scraping down the bowl with a spatula, and whipping again. Put a couple of raspberries in the bottom of each wineglass. Spoon a layer of whipped cheese over raspberries. Sprinkle with white chocolate and crumbled biscotti. Continue to layer raspberries, whipped cheese, white chocolate, and biscotti with remaining ingredients. Refrigerate for 2 hours and serve chilled. Parfaits can be refrigerated longer but the biscotti will gradually lose its crisp crunch.
